The goal of operational Business Intelligence (BI) is to help organizations improve the efficiency of their business by giving every “operational worker” insights needed to make better operational decisions, and aligning day-to-day operations with strategic goals. Operational BI reporting contributes to this goal by embedding analytics and reporting information into workflow applications so tha...

Cool stars on the main sequence generate X-rays from coronal activity, powered by a convective dynamo. With increasing temperature, envelope becomes smaller and X-ray emission fainter. We present Chandra/HRC-I observations of four single with early A spectral types. Only coolest star this sample, $\tau^3$ Eri ($T_\mathrm{eff}\approx8\,,000$ K), is detected $\log(L_X/L_\mathrm{bol})=-7.6$ while ...

Colonization of soft lining materials with microorganisms, espe­ cially Candida albicans, is a common clinical problem. Silicone­based soft li ning materials have been found to be particularly susceptible to Candi­ dal adhesion. This study investigated the Candida albicans adhesion to 6 silicone­based soft lining materials (Molloplast­B, Mollosil, Ufigel P, Ufigel C, Soft Liner and Luci­sof). F...

Developing elementary behavior is the starting point for the realization of complex systems. In this paper we win describe a learning algorithm that realizes a simple goal-reaching behavior for an autonomous vehicle when a-priori knowledge of the environment is not provided. The state of the system is based on information received by a visual sensor. A Q-learnlng algorithm associates the optima...

ow quickly time flies! It has now been a decade since eporting the first randomized trial of coronary stenting for cute myocardial infarction (AMI). At that time, it was hocking to think that one could place a metal foreign body nto a thrombogenic milieu and expect the artery to remain atent. Hence, we and others conducted several randomized rials comparing primary angioplasty and stenting, and...

The value of travel time savings (VTTS) is the monetary value attached to save a determined amount of travel time. VTTS is also the most important benefit category aimed at justifying investments in transport infrastructures by public administrations. Hence VTTS played a significant role in various economic studies, both analytical and empirical (Zamparini & Reggiani, 2007). "It is difficult to...

 Contribution change of factor costs analysis may help managers in decision making and in adjusting to changes. Over the last two decades, production and enhancement of kutum fingerlings have increased in Iran, reaching to more than 229 million fingerlings by 2005, but declined to 187 million from 2005 to 2008. Over the years 2002-2006, a study of fingerling production costs for kutum fish was ...
